Our invention relates to l devices for securing demountable rims to vehicle wheels. x

The principal object of the invention is to provide means which are almost instantly attachable to or detachable from a permanent rim and the felly whereby to permit the detachable rim and thereby the tire to be removed from or replacedon the vpermanent rim in an extremely quick period of time.

A further object is to provide a device which, when once positioned, cannot be removed except in the manner intended for its removal. Y i

Another object is to provide a device which will not readily be adected by moisture, mud, sand, grit norany other ofthe injurious things to which tires are subjected.

Another object is to generally simplify and improve the construction and to 1ncrease the utility and efficiency of devices of this character. y

To the vattainment of the foregoing -and other ends, the invention relates to improvements in the structure, to certain-novel combinations, and to the adaptation of parts be Omltled) of 'the rectangularly arranged tures of the 'same are susceptible of numerons changes in details, structure and structural arrangements, certain practical embodiments of which are shown inthe accomwherein l:

vlows: Assume the parts to have been placed To lock the demountable rim 3 and thereby the tire 2 on the xed or permanent rim 5 the nut 17 is to be given a one-half revolutionin the direction to thread it onto the 'bolt 1 8.V The head 16 will cam over-'the ont j standing spring 13, forcing the free end of the latter inwardly, until the head 16 strikes anddrops into the recess or pocket' 15,-thus forcing the convex portion thereof inte the pocket 11, whereupon said spring will instantly expand and bear against the head of the nut, thereby tending to draw it away lfrom' the head of the bolt 18, which head, bearing againstthe telly, will be drawn iore tightly thereagainst and the plate 7 be forced toward the rims and felly to lock .the detachable rim 3 rigidly between the clip-projection 9 and the flaring arm of the fixed rim 5', with the detachable rim resting firmly and evenly on the hinner edge of said arm and on the yrim supporting flange or projection 8 of the clip. The nut cannot -move after this operation, for the expanded spring is bearing firmly against it and a portion of the head of the latter is resting l the bolt and nut are identical with those shown in the principal figures and therefore likewise numbered,'the clipis formed of a single piece of spring metal consisting of a base 7 comprising one end and an intermediate portion of a plate, folded at its lov'ver end to form a pair of ears 21 which are united at their upper ends in a V-shaped pocket 15, the back plate of the base being bent to form a rim-supporting flange 8 and V-being slotted similarly to the front piece of the base 7 In the modification shown in Figs. 7 and 8, the spring 13 substantially V-shaped, its branches or leaves slotted for the passage of the bolt-head 16 and the front one having a pocket 15` for'the engagement of said head. 32 indicates a plate fixed by a screw 33 tothe'felly 4. 8" designates a casting secured by rivets 34 to the inner leaf of the spring and serving the same purposes as does the flange or projection 8 of Fig. 1.

Now see Figs.j9 and 10.' 7a designates a base having a transversely arranged rimedge-receiving recess 9a, receiving pocket 11a, a nut-head-passage slot 10a, and a curled bottom 40 adapted to receive and be bent or driven down onto, to fasten therein the lower end of a spring 13a having a projection 15a.

Inl Fig. 11 the clip is shown as formed of a. single piece of metal having a base 7, a., rim-supporting flange 8", and a spring 13c provided with a pocket projection 15e.

It is provided'also with slots for the pas` sage of the bolt-head 16.

In Fig. l2 I have shown the head 16 as and a detachable rim, of a a spring-projection on the bolt instead of on the nut as in all the other figures. 50 designates the bolt, and 51 the nut. 52 indicates a V-shaped or apertured plate provided for the same purpose as is the plate 32 shown in Fig. 8, namely, to furnish a metal base for the bolt.` 7l designates a base very similar to that shown in Figs. 1, 2 and 3 and has a. rimsupporting flange 8c and a rim-binding liange 9C. The spring is substantially V-shaped and is secured by rivets 12c to the base 7C. 15c designates the pocket in said spring, adapted to be engaged by the head 16 of the bolt 50.
